Switches that use ____ forwarding start sending a frame immediately after reading the destination MAC address into their buffers.
A) cut-through
B) store-and-forward
C) fragment-free
D) adaptive cut-through forwarding

Question

Quizplus · Accepted Answer

Cut-through forwarding switches start forwarding frames immediately after reading the destination MAC address without waiting for the entire frame to be received or verified. This results in lower latency, but there is a higher risk of forwarding corrupted or incomplete frames. Store-and-forward forwarding switches wait for the entire frame to be received and verified before forwarding it, resulting in higher latency but fewer errors. Fragment-free forwarding is a variation of cut-through forwarding that reads the first 64 bytes of a frame, which is typically where errors occur, before forwarding it. Adaptive cut-through forwarding is a dynamic method that adjusts between cut-through and store-and-forward depending on network conditions.
